VEHICLE-SEAT LOCK.

SPECIFICATION formingpart of Letters Patent No. 81,600, dated July 17, 1883.

- Application filed February 15, 1883. (No model.)

.To @ZZ whom it may concern.-

Be it known that I, RoMAN'rA D. WOOD- FORD, a citizen o f the United States, residing at Cortland, in the county of Cortland and State of New York, have invented certain new and useful Improvements in Automatic Wagon-Seat Fasteners; and'I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

My invention relates to wagon and' other seats, and means for securing them to the bodies of wagons or other vehicles; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and specifically pointed out in Dowel-pins, bolts, and guides, and other devices, have been before employed'in this connection; but these constructions, so far as known to me, have lacked the quality of locking the seat against upward movement, as well as the wagon sides against lateral movement.

The object of this invention is to provide a locking attachment between the seat and body or support which will prevent longitudinal, lateral, or vertical movement, will be automatically locked when placed in position, will be simple and cheap of construction, readily attached, durable and efficient in service, and readily unlocked when it is desired to remove or change the position of the seat.

To these ends the invention consists in the mechanisms fully illustrated in the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view of a wagon seat and body with my improved fastening device in position; Fig. 2, atransverse section of the same, and Fig. 8 a perspective view of the three parts detached and slightly modiiied.

For convenience I will describe the device as applied to road-wagons or similar vehicles; but it is obvious that it may be employed in other relations with equal efficiency Aand convenience without either `departing from the principle or sacrificing the advantages of my invention, the essential features of which will now be described.

Referring to the drawings, in which similar letters of reference indicate like parts in all the iigures, A indicates the base-frame, having a longitudinal recess, a, adapted to receive the shank b of a hooked tongue, B, and a bridge, a', under which said tongue operates, a spiral spring, C, serving to hold the tongue in constant contact with the frame A, except when the force o f the springs is overcome. The tongue Bis preferably pivoted or journaled in the head a2 of the base-frameA by the same means, c3, which assists to secure the device to the seat-standards, and the hook Z/ is inclined inward, as shown, to correspond with the engaging-surface d of the staple D. The spring C lits at one end neatly over a lug, b2, upon the tongue, and at the other upon a similar lug or teat, at, formed upon the lower or inner side of the bridge a'.

The frame A and tongue B are secured by screws to the seat-standards, and the stapleD to the body sides of the vehicle. The side of the staple next to the joint is beveled, as shown at d, in order that the contracting beveled surface b3 of the tongue may ride up the same and automatically overcome the force of the spring C when the seat is placed in position, and the frame A is provided with a projection, A, which, in the same operation, passes through the bridge formed by the staple D.

Dowel-pins and corresponding recesses may be provided between the bearings of the seatstandards and body sides, if desired; but these features are well known and form no essential part of this invention.

In the modication shown in Fig. 3 the tongue B has a cross-journal, which has a bearing in the frame A but I prefer the construction wherein the tongue is pivoted upon the securing screw or bolt.

It will be observed that the staple D and frame A, having projection A, prevent the body sides from spreading or moving inward, while the hook, in connection with said staple, prevents the displacement of the Vseat vertically.

What I claim as new is- 1. As a means for securing a seat to its bearings, a base-plate secured to the seat and hav- IOO ing a. projection which oper-tes under a staple to prevent lateral ploy7 and :L springwtongue hm'ng u hook which engages the Said staple upon its outer side, und pivoted by Jshe same means which secures the buse-plate to the seat, :is set forth.

2. In combination with the frame or base plate A, having projection A', head and bridge a', the tongue B, having hook b', bevio eled surface b3, :md pivoted by the securingscrew a3, the spring C, and the staple D, hav ing beveled surface d, all constructed and. :Lrranged to operate as mid for I[he purposes Set forth.

In testimony whereof I adix mysignaturen l presence of two witnesses.
